Abstract: A Mach-Zehnder (MZ) modulator includes a splitter, two modulation arms, and a coupler. The two modulation arms include two optical transmission waveguides and two electrodes. The splitter is configured to perform power splitting on an optical carrier to obtain two optical carriers and input the two optical carriers to corresponding input ports of the two optical transmission waveguides, respectively. The two electrodes include a first electrode and a second electrode which are respectively configured to receive two differential electrical signals and apply the two differential electrical signals to the two optical transmission waveguides to change phases of the two optical carriers. Two input ends of the coupler are connected to output ports of the two optical transmission waveguides, respectively, and are configured to perform interference on the optical carriers whose phases are changed via the two modulation arms and output the optical carriers.

Abstract: This application provides an optical communication system, a vehicle, and an industrial optical network, and relates to the field of optical communications. A light source module in the optical communication system can be connected to a group of first nodes separately through two carrier bearer networks. Therefore, even if either carrier bearer network is faulty, the other carrier bearer network can continue to transmit an optical carrier, thereby effectively improving reliability of optical carrier transmission, and further improving reliability of the optical communication system. In addition, because the two carrier bearer networks are independent of each other and can work simultaneously, after either carrier bearer network is faulty, no failover is needed. This can avoid interrupted transmission of the optical carrier caused by the failover, and further avoid interrupted transmission of a service optical signal.

Abstract: Examples of a polarization independent optical device are described. One example polarization independent optical device includes an input/output preprocessing optical path and M add/drop optical paths. Any add/drop optical path can be configured to drop a first QTE and a first PTE that meet a resonance condition of a microring included in the add/drop optical path such that each add/drop optical path can be configured to drop a desired optical signal. Any add/drop optical path can also be configured to transmit an input optical signal to the input/output preprocessing optical path. Therefore, when any of the M add/drop optical paths is configured to drop a desired optical signal, another add/drop optical path can be configured to add a desired optical signal.
